GEORGE B. RICHARDSON, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO HIMSELF, THOMAS T. SANBORN, AND WILLIAM M. COBB:

lMiROVED SALT BOTTLE OR CASTER.

Spec'ieation forming part of Letters Patent No. 71,643, dated December 3, 1867.

To all 'whom 'it 'may concern.'

Be it known that I, GEORGE B. RICHARD- SON, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Im- Y ings, making part of this specification, in

l pulverizer detached.

which- Figure lis a central vertical section through a salt-bottle having my improvement applied thereto. Fig. 2 is a perspective view of the The ordinary salt-bottle is objectionable, for the reason that when the salt is caked together from dampness it cannot be easily shaken out through the perforated cap. To overcome this difficulty, a stationary rod provided with arms has been placed within the bottle or box, so as to pulverize the salt when the latter is dashed against them in the act of shaking. This device, however, does not ac complish the desired object, as it forms a stationary obstruction within the bottle, around which the salt is liable to be caked'together `in lumps and held down, so that it cannot be shaken ont as required.

To overcome the above-mentioned difficulties is the object of my invention, which consists in placing within a salt bottle or box Aa movable rod or pulverizer, which is enlarged at each end and provided with points or projections, so that when the bottle is shaken the pulverizer will move within it and effectually break up the salt, so that it can escape freely through the perforated cap 5 and my invention consists, in combination with the above, in

\placing a piece of cork or other suitable material at the bottom of the bottle, so as to deaden the blow of the pulverizer and pref vent it from breaking or cracking the bottle when the latter is empty, or nearly so.

To enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents a glass salt bottle or receptacle provided with an orif dinary perforated screw-cap, a. Within the bottle A is placed the pulverizer B, which is made of cast metal or other suitable material, and consists of a rod, the extremities of which are enlarged at b and provided with points or projections c d, which, when the bottle is shaken, strike against the salt and pulverize it, so that it will escape freely through the cap a., as required. The heads b ofthe pulverizer may be provided with any desired number of points or projections, placed in position best suited to effect the object for which they are intended.

It will be seen that the pulverizer B, being detached from and moving freely within the bottle, forms no stationary obstruction to hold the salt when damp and caked together, as is the case when a shaft provided with arms is fixed permanently within the bottle.

e is a disk or layer of cork, which, when the bottle is empty, or nearly so, serves to receive the end of the pulverizer and prevent it from breaking or cracking the bottle when shaken. If, however,the bottle or receptacle A, instead of being made of glass, is formed of metal or other strong material, the disk e will not be required.
